摘要：Component-based software development (CBD) is an emerging discipline that promises to take software engineering into a new era. Building on the achievements of object-oriented software construction, CBD aims to deliver software engineering from a cottage industry into an industrial age for Information Technology, wherein software can be assembled from components, in the manner that hardware systems are currently constructed from kits of parts. Component-based development (CBD) is a branch of software engineering that emphasizes the separation of concerns in respect of the wide-ranging functionality available throughout a given software system. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software. Software engineers regard components as part of the starting platform for service-orientation. Components play this role, for example, in Web services, and more recently, in service-oriented architectures (SOA), whereby a component is converted by the Web service into a service and subsequently inherits further characteristics beyond that of an ordinary component. Components can produce or consume events and can be used for event driven architectures (EDA).
